Large-leaved Aster (Eurybia macrophylla)

Large-leaved Aster

Eurybia macrophylla

Large-leaved Aster is a perennial that grows 1 to 4 feet tall, notable for its large, heart-shaped basal leaves and clusters of pale blue to white flowers that bloom from late summer to fall. It thrives in deciduous and mixed woodlands, preferring shaded areas with rich, moist soils. This species provides late-season nectar for pollinators and serves as a pop of color in shaded gardens and woodland settings, helping to suppress weeds and stabilize soil.

Sowing Information

Sow seed onto a firm, weed-free seedbed. Hand-broadcast seed making two perpendicular passes for even coverage. If planting a mix, broadcast the grass component first and lightly rake/drag it into the top 1/8–1/4" of soil. Next, broadcast wildflower/forb seed and press it into the soil surface (with a roller/cultipacker or the back of a rake) to ensure good seed-to-soil contact. After seeding, apply a very light layer of clean, seed-free straw (or other weed-free, site-appropriate mulch) to reduce erosion and retain moisture without smothering seedlings. A good rainfall or thorough watering will help settle seed and mulch and improve germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
